Two parts, each with two holes, are to be pinned together by some type of fastener. Nominally the holes on part 1 are to match the holes on part 2 and the fastener diameters should be smaller than the hole diameters. Due to variation in hole diameters, fastener diameters and hole center positions loose pinning of the two parts may no longer be possible. The problem considered here is to define ...

We describe a numerical model for chip level lithography variability analysis. Gate level critical dimensions are adjusted based on lithographic variability simulations and these perturbed gate lengths are input to a chip timing analyzer. Statistical modeling studies highlight the interaction between lithography variability and chip timing performance including the role of lithography error cor...
